Fitted my DTUK box on cupra 280 and really impressed with the improvements. Running it on 3+3 and over the couple hundred miles I've done it feels a lot more responsive and more of a power surge than before. Thought I'd get the tyres spinning a bit more but once in 2nd gear it wasn't an issue really in the dry. 10/10! Only took 20 mins to fit as well which was a bonus
